Im still being charged for a game I unsubscribe from back in February

This means that you did not purchase the subscription through Apple, but directly with the app developer or elsewhere.

So contact your bank.

For sure see ⤵️

Looks like that the invoice is not from Apple, is this correct?

You didn't give an answer.

Contact your bank, they can find out who (name, address & account number) has collected the amount from your bank account, and when.

Depending on your bank, they can collect the amount back within 30 days.

Ask also your bank to block your card, and ask a new card.

Also report to the police.
